Definitions

  • the present invention relates to a series of improvements introduced in the watertight coupling system for prefabricated chimneys and modular ducts constituting the object of the invention patent P200201060.
  • the object of the invention is to achieve, while maintaining the essentiality of said coupling system, optimum guarantees in the sealing thereof.
  • patent P200201060 a tight coupling system for chimneys and prefabricated modular ducts is described, based on the metal-metal fit without complementary joints of synthetic materials, in which at least one of the coupling ends has a conical trunk shape. and it is connected to the other coupling end by tongue and groove, contacting both overlapping surfaces through one or more tangency annular lines or small annular contact surfaces, all with an established axial pressure when coupling.
  • one of the driving sections is perfectly cylindrical, lacking any type of annular shoulder on the surface of the cylinder, while the other is trunk- conical, receiving the first one under pressure or penetrating into it, achieving the immobility in the axial direction of a conduction module with respect to another and the metal-metal sealing by elastic or permanent adaptation of the two coincident surfaces in the area of coupling.
  • the duct modules overlap each other through a wide essentially cylindrical sector, in which either one of the modules or both modules simultaneously, incorporate annular projections of pressure coupling on the other module, which can either be oriented inwards and / or outwards , depending on which module or modules to join are located.
  • Figure 1 shows a view in side elevation and in section to a quarter of the coupling of two tubular modules in accordance with the improvements of the invention, and more specifically in accordance with an example of practical embodiment in which a cylindrical module penetrates at the trunk-conical and divergent end of the other.
  • Figure 2 shows a representation similar to Figure 1, but corresponding to a practical embodiment of the opposite sign, that is, in which the trunk-conical end of one of the modules penetrates the cylindrical end of the other.
  • Figures 3 and 4.- They show similar representations to those of figure 1, in which the female element extends beyond its trunk-conical sector in a cylindrical sector that is related to the other module through one or more of annular projections, located in figure 3 in the outer module and in the figure
  • Figures 5 and 6. They show representations similar to those of Figures 3 and 4, but applied to a tongue and groove coupling solution like that of Figure 2.
  • Figure 7 shows a coupling solution equivalent to that of Figure 3, but in which one or more annular ribs are established, one on the outer or enveloping piece and another on the inner piece.
  • Figure 8 shows, finally, an embodiment similar to that of Figure 5 but in which, as in the case of the previous figure, one or more annular projections are also established, one on the envelope or outer module and another on the inner module.
  • the module (1) incorporates a trunk-conical and divergent end (3) that when receiving in its bosom the free edge (4) of the module (2), perfectly cylindrical or with a flange folded at its end, establishes a perfect metal fit- metal that ensures perfect tightness, while in the case of figure 2, with a similar simplicity, of the two tubes to be joined (5-7), the tube or module (5) is finished off in a trunk-conical and convergent section (6) that penetrates into the inside of the cylindrical module (7) establishing with the free edge (4) of the latter a perfect determining adjustment of the same degree of tightness as in the previous case.
  • the module (8) finished off in a trunk-conical and divergent section (3) extends beyond the latter in an essentially cylindrical sector (9) equipped with one or more annular embossments (10-10 '), with a half-round profile, which with their outward-facing concavity determine annular lines of contact on the external surface of the other module (11), perfectly cylindrical.
  • Figure 7 starts from a structure similar to Figure 3, in which a module (15), equivalent to the module (8) of said Figure 3, incorporates a trunk-conical and divergent section (3) beyond which a cylindrical sector (16) of considerable axial height is established, provided in its inner half with one or more perimeter grooves (10-10 '), while the inner module (17), which penetrates into The module (15) until reaching the trunk-conical section (3) of the latter, incorporates one or more annular projections (10-10 '), intended to contact the external surface of the terminal sector (16) of the module (15) , and beyond which a cylindrical sector (18) is established with which in turn contacts the pressure of the annular projections (10-10 ') of the outer or enclosure module (15).

Abstract

A partir d'un ajustage métal-métal sans joints complémentaires en matières synthétiques, dans lequel un des modules à relier (8) se termine en un segment tronconique (3), lequel se couple mâle-femelle à l'extrémité cylindrique de l'autre module (11), les améliorations de l'invention résident dans la prolongation de ce segment tronconique (3) en un tronçon cylindrique étendu (9), doté d'un ou plusieurs épaulements annulaires (10-10') qui déterminent deux lignes annulaires tangentielles et dans l'accouplement par pression sur le module (11), au niveau de zones essentiellement cylindriques qui tendent à maintenir, outre l'étanchéité, la stabilité axiale entre les modules.
